What causes this issue?

The system tried to assign Standard order &V1& to an agreement type (a
rebate agreement, for example). No billing type for the order-related
billing, however, has been assigned to the standard order which you
have chosen. This order type is essential to make a correction or
settlement.

System Response

The system does not allow any further processing with this order type.

How to fix this error?

Either choose another order type or change the order type which you
have already chosen by maintaining in Standard order &V1& the billing
type for the order-related billing.
